If your heater keeps shutting off unexpectedly, there are a few common steps you can try to fix the problem:
- Check if the Air Filter is Dirty or Clogged:
A clogged air filter is one of the most common causes for a heater shutting off. When airflow is restricted, the system can overheat and trigger a safety shut-off. Check your filter and replace it if it looks dirty or hasn’t been changed in a while. - Check the Thermostat:
If your thermostat isn’t calibrated correctly, it might signal your heater to turn off too soon. Make sure your thermostat is set to ‘heat ’ and not just ‘fan’, and the temperature is above the current room temperature.
